 Different stacks will need different shifts to make a good looking stereo pair.  To help in finding a good shift, Zerene Stacker provides a simple stereo previewing facility.  Just go to Tools > Stereo... > Start Preview.  This will set up two side-by-side synchronized windows that act like Retouching except that there’s no brush and you can choose whatever output image you want in either window.  Just click on the window, then click on an entry in the Output Images list.  Repeat for the other window, and adjust your selections until the two images work well together.   Different stacks will need different shifts to make a good looking stereo pair.  To help in finding a good shift, Zerene Stacker provides a simple stereo previewing facility.  Just go to Tools > Stereo... > Start Preview.  This will set up two side-by-side synchronized windows that act like Retouching except that there’s no brush and you can choose whatever output image you want in either window.  Just click on the window, then click on an entry in the Output Images list.  Repeat for the other window, and adjust your selections until the two images work well together.  
  
- +Note that for some stacks the images may initially appear in the wrong order, so that depth is inverted.  In that case, you can reverse the order of the images in preview with four mouse clicks: select left window, select the Output Image to appear in the left window, select right window, select Output Image to appear in the right window.  If you consistently find that you need to reverse the order in preview, you can also change Preferences so that the images are created in the opposite order to start with.  Simply go to Options > Preferences > Stereo/Rocking and swap the values for first and last image shifts.  For example if -3,+3 produces images in reversed order, then swap them to be +3,-3. 
  
 Here is what the screen looked like when Stereo Previewing the sample shown above.  The left window is showing image _002, as indicated by the highlighted title bar and highlighted image name.  The right window happens to be showing image _006, although we can’t tell that from this screen capture.   Here is what the screen looked like when Stereo Previewing the sample shown above.  The left window is showing image _002, as indicated by the highlighted title bar and highlighted image name.  The right window happens to be showing image _006, although we can’t tell that from this screen capture.
